I just bought two dozen medium wide prefolds, two dozen large prefolds, and six flats. I figured I'd just prep the mediums together with the flats, but would it be too much to do it all together? I have a whirlpool duet FL washer and dryer.
I think that sounds okay. It might be a big load but it's not like they have pee and poo in them. You're just trying to get the oils out and quilt them up. I might use the add water button if you have it or get them all wet before you start the machine.
